-- "In machines trit types disclosedby the above-mentioned patents,there is a main frame" or body supported on four iordinary 'wheelsadaptedtofrest on track rails or on the ground; On the frame or body is:aforlwarddirected jib on which isan endless apronin front of which'is ashovel associate'dywith nieanslforactuating the shovel for taking'material from the grounder-floor and delivering the materialto theendless apron to be carried backward for discharge from the rearendofthem'achine, fj

F5, and rests"rotatably inj'the outer bearby the shovel and saidshaftare"; compelled to rockin'unison.*-

The forward part'of each'bearing p'iece, F1, is rounded concentric withthe shaft, F6. Thus a semi-circular edge is formed. A' cast steel boot',F11,is curved to'be concentric with the .shaft,F6; and has its endsbearing against the inner'face of the semi-circular part of eachbearingpiece, F1." (Fig. L5.)

At each bearing-plat'ethere is a side plate,

obliquely'forward and outward. 'The' rear edge of the shovel bottom, F7,iscut tomeet the front face of the boota-nd the oblique faces of the'platesf, F13,- The upright sides,fF8

,C p screws, F12, extend horizontally through the connection between theboot and the bearing F13, which reacheslover a part ofthe adjacentforward face ofthe boot, F11, and thence Shovel 0 pe'r'at'ion Inoperation, the shovel is to be in approximately the horizontalposition-usually with its lip on the fioorwhile the entire machine ismoved forward to drive the shovel under the material which is'to beloaded. When the shovel is thus under the material, it is: to

be turned on the shaft, F6, to which the lower bearings, F10, of theshovel are secured, as already described. g

This turning .of the shovel raises its forward part until the bottom,F7, of the shovel is about even with the upper edge of the boot, F11,and is sufiic ientlyinclined toward the conveyor belt to cause thematerial on the shovel bottom to slide downward and rearward onto theconveyor belt. When the material has been thus discharged, the shovel isto be turned in the reverse direction to again be in position to receivemateria'l by being moved forward by the bodily forward movement of themachine, These movements of the shovel are to be carried onindefinitely. The mechanism by which these movements are effected. willnow be described.

At each side ofthe shovel, a wrist, F15, eX- tends outward from theupper bearing, F9, and into the bearing, F16, on the forward end oftheadjacent pitman rod, F17. The rear end of said pitman rod has a bearing,F18, which receivesthe wrist, F19, on the crank, F20, which is fixed onthe crank shaft, F21, which rests in bearings, F22, seated on the sidemembers, C24,.of the jib yoke.

longitudinal strainson said rod. wardsectionof the rod 1s-.fixed theforward On eachpitman rod, F17, is a turn buckle, T, threaded in theusual manner'on two sections of said rod. (Figs. 1 and 2.) At one endofthe turn buckle a jam,nut,jT1,.surrounds the rod. Its function is to setor bind the turn buckle after the buckle has been adjusted for varyingthe length of the rod.

This turnbuckle is to be regarded as. screw mechanism for manuallyadjusting the length ofthe rod. On each pitman rod is also placedcushioning means for yieldingly resisting On theforend of a-:-bar re'l,S. In the rear end of said barrel is a -bearing,S1, in which restsslidably the middle section of the rod, F17. On

the forward end of said section isfixed a head, S2, which is slidable'in the barrel, S. Between said head and the bearing, S1, an

expanding coiled spring, S3, surrounds said middle section andyieldingly resists'forward movement of the bearing, S1, and the barrelforward part of the shovel.

S, and the forward section of the rod and the shovel bearing, F9,whereby limited downv ward movement of the front of the shovel isyieldingly resisted. Withinthe barrel and in front of the head, S2, isan expanding coiled spring, S4, which yieldingly resists rearwardmovement of said barrel and the forward section of the rod and theshovel bearing, F9, and upward movement of the Permitting such upwardmovement of the shovel is desirable when the lip of the shovel, duringits forward movement, meets a rising surface, and such downward movementis desirable when the lip of the shovel meets a descending surface. Saidsprings also permit yielding as may be required when the forward partpofthe forward jibsection rises or descends rel,- ative to the forward partof the rear section of the jib, as will be described further;

Such movement is then needed, because on. the crank shaft and the hingeof the forward j ibsectio-n are not in the same axialline;

For driving the crank shaft, F21, a sprocket wheel, F23, surrounds thecrank shaft, F21, between the right hand crank, F20, and the adjacentbearing, F22, and hasahub, F24, seated in and extending through thebearing,

F22. V The part of the hub whichextends beyond the bearing is flangedoutward to overlap the outer end of said bearing forholding said hubagainst outward. movement through said bearing. '(Figs. 1 and 2.) Saidend of the hub is also notched to make one member of a toothed clutchwhich is adapted to'be engaged by the sliding keyed F30,securedto]theinner face of theright hand yoke member, C24, and havingits rear endcoupled to :means for shifting (not shown). When the forward end of thelever, F29, 1s driven toward the. right, the clutch -men1ber, F25, isdriven into engagement with .the hub, F24, of the wheel, F23. Then thecrank shaft, F21, receives rotation fromxthe sprocket wheel, F23. Thenthe. cranks F20,

are turned and eachpitman isIreciprQcated for the reciprocation of thebearings, F9, of the shovel, whereby the shovel is put through itsmovements. v I claim as my invention, In a shoveling machine, thecombination with a jibof a shovel having bearings, a pair of duplexbearings at the forwardend of the jib, said bearings being on a commonaxial line whichis horizontal and transverse to the length of the jib,the inner bearing of each pair being'of larger diameter than the from asource of power not adjacent outer bearing, a rotary tubular shafthaving one end resting in one inner bearing and having its other endresting in the other inner bearing, conveyor Wheels surrounding andfixed to said tubular shaft adjacent each inner bearing, and a shaft ofsmaller dia1neter extending loosely through the inner bearings andresting in and extending through the outer bearings and into the shovelbearm s. i in testimony whereof I have signed my name, this 7th day ofSeptember, in the year one thousand nine hundred and twenty-seven.
